Swap in your browser — non-custodial
Pick a pair and amount, deposit to an address only this browser controls, and receive the other coin via an atomic swap. The site server never sees your keys or coins; if anything stalls you reclaim exactly what you deposited. Testnet only.
The swap runs entirely in this tab against the maker over a relay that only passes messages. How it works →
Keep this tab open
An atomic swap needs your browser to finish its half (claiming the coin you’re buying). Closing the tab mid-swap is safe — you can reclaim your deposit after the refund deadline — but leaving it open lets the swap complete on its own.
Your keys, this browser
Each swap uses a fresh key generated and held only in this browser (localStorage), used once and then done. The deposit address is yours; nobody else can spend it.
